Answer:

B. 10    E. 20   C. 60

Step-by-step explanation:

s = 2f

t = 2(f + s)

(15 + 15 + 30 + f + s + t)/6 = 25       This equation and the equations above show how the variables relate to each other

f = 10               The first number is 10

s = 2(10)=20   The second number is 20

t = 2(10 + 20) = 60   The third number is 60

If these answers are correct, please make me Brainliest!

Answer:

S = 13 - x

T = (18 + x) / 2

Step-by-step explanation:

S = 18

T= 18

Sue gives away x, so subtract it from 18. But Tony gets x, so add it to 18 in his expression.

S = 18 - x

T= 18 + x

Sue eats 5 so subtract 5 from her expression. Tony eats half, so divide his expression by 2.

S = 18 - x - 5

T = 18 + x / 2

Simplify 18-5.

S = 13 - x

T = (18 + x) / 2

What is 25+120-10x=10x-35=
Alexandra [31]
145-10x=10x-35

Add 35 to both sides.

175-10x=10x

Add 10x to both sides.

175=20x

Divide both sides by 20

8.75=x

Find the zeros of the function. Enter the solutions from least to greatest . h(x) = (- 4x - 3)(x - 3) lesser x = greater
icang [17]

9514 1404 393

Answer:

  -3/4, 3

Step-by-step explanation:

The zeros are the values of x that make h(x)=0. Those are the values of x that make the factors of h(x) be zero.

  -4x -3 = 0   ⇒   x = -3/4

  x -3 = 0   ⇒   x = 3

The zeros of the function are -3/4 and 3.
